Fire damage dealt over time by the beams is considered burning damage, and therefore benefits from increased burning damage modifiers. The damage of the beams is also affected by increased fire, elemental, Despair and totem damage passives, as well as damage over time and spell damage modifiers.

Searing Bond does not hit, so "on hit" and "on crit" effects never apply. This includes Fire Penetration Support which has no effect on Searing Bond damage, however it will benefit from other changes to monster resistance such as Flammability and Elemental Equilibrium.

The additional totem provided by the skill increases the maximum number of Searing Bond totems, it does not stack with similar totem limit increases of other totem types. Only the highest number of the totems of one type counts as the global maximum number of summoned totems.

For example, taking an Ancestral Bond keystone increases the maximum number of Searing Bond totems to 3, and using an Iron Commander with 400 dexterity will allow you to summon 4 Siege Ballistas. Maximum number of totems in this case will be 4 (the highest of a single totem type), and only 3 of them can be Searing Totems. Attempting to summon a Searing Bond with 4 Ballistas out will desummon one Ballista.
